Remove direct reservation management from web interface

PROBLEM:
Direct deletion/creation of reservations via web interface bypassed
POS business logic, creating data inconsistencies (orphaned showcase kits,
incorrect stock calculations).

SOLUTION:
Make reservations read-only in web interface. All reservation management
now happens only through:
- POS (showcase kits)
- Orders module

CHANGES:
- Remove reservation-create and reservation-update URL routes
- Delete ReservationCreateView and ReservationUpdateView
- Remove ReservationForm (no longer needed)
- Delete reservation_form.html and reservation_update.html templates
- Update reservation_list.html to read-only view with info banner
- Add showcase and order columns to reservation list
- Clean up imports in urls.py and views/__init__.py

Reservations are now read-only for monitoring purposes only.
